Tankless water heating Tankless models don’t store hot water. When hot water is needed, water flows through the device and the flow sensor fires the burner. Water lines around the heat exchanger warm the water to the desired temperature.When the hot-water valve is closed, the flow sensor turns off the burner.ankless models don’t store hot water.

What Is Elastic Demand? Formula, Curve, and Examples The quantity demanded will change much more than the price. As a result, the curve will look more low and flat than the unit elastic curve, which is a diagonal. The more elastic the demand, the flatter the curve. The graphic above shows the perfectly horizontal line of a perfectly elastic demand curve.

How Tankless Water Heaters Work In a traditional heater system, there's a large tank that holds and heats water. In order to give you hot water when you need it, the tank continually heats the water to maintain a constant temperature. The energy used to keep the water hot even when it's not being used is called standby heat loss.
